From cee2824f85414c98fff4004e335a6bc4072c8809 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 3 May 2005 22:04:36 -0700 Subject: [PATCH] [SPARC64]: Fix goal_cpu tracking in retarget_one_irq(). We would never advance the goal_cpu counter like we should, so all IRQs would go to a single processor. Signed-off-by: David S.
